1. Find the margin of error for the given values of c,s,and n
c=0.95,s=3.1,n=81
2. Construct the confidence interval to find the estimated margin of error. Then find the sample mean.
A biologist reports a confidence interval of (3.3,4.5) when estimating the mean height (in centimeters) of a sample of seedlings.
3. You are given the sample mean and the sample standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient, use technology to construct the confidence intervals.
